Police on Thursday arrested a New Jersey man who they said had confessed to the 1979 killing of 6-year-old Etan Patz in a case that drew national attention to the plight of missing children and had frustrated law enforcement officials for more than three decades.
New York Police Commissioner Raymond Kelly said Pedro Hernandez, 51, confessed to luring the boy to the small food market where he stocked shelves with the promise of a soda, then choked him and disposed the body in a plastic bag he threw in the trash.
Mr. Hernandez will be charged with second-degree murder, Mr. Kelly said, capping a day of dramatic developments in the case. Friday would be the 33rd anniversary of the boy's disappearance from New York's SoHo neighbourhood.
The arrest came a day after police picked up Mr. Hernandez in Camden, New Jersey, for questioning in the case, working off a tip to the missing-persons unit. Mr. Hernandez admitted to the killing under questioning, during which he appeared "remorseful" and expressed "a feeling of relief," according to police.
The commissioner said Mr. Hernandez had previously talked about the incident with a family member and others, telling them "he had done a bad thing and killed a child in New York," Mr. Kelly said.
"We can only hope these developments bring some measure of peace to the family," Mr. Kelly said.
The break in the case came one month after the FBI and New York City Police conducted a four-day excavation of a basement on the block in SoHo where Etan lived and was last seen. At the time, police said no obvious human remains were found and it remained a missing person case.
Kelly said the tipster came forward earlier this month following the recent publicity surrounding the Patz disappearance on May 25, 1979, when his parents allowed the boy to make his first unaccompanied trip to the bus stop two blocks away. They never saw him again.
Mr. Kelly said Mr. Hernandez, who was 19 at the time, was not questioned when the boy went missing, even though police had visited the grocery store during the investigation.
The store, on the same corner as Etan's bus stop, has since closed and is now an eye glass shop called "J.F. Rey."
Mr. Kelly said police were still working on a motive, but believed Mr. Hernandez worked alone and did not sexually molest the boy, who was formally declared dead in 2001.
There is no physical evidence in the case, but Mr. Kelly said detectives "believe in the credibility of Mr. Hernandez."
At the time of the killing, Mr. Hernandez lived in the SoHo neighbourhood, but has since moved to Maple Shade, New Jersey, just outside Camden, where neighbours on Thursday described him as a quiet man who showed no outward signs of a darker past.
"The family was never a problem. He cut the grass. He shovelled snow. He didn't bother anybody," said Dan Wollick, 72, a retired garbage truck driver who lives downstairs from Mr. Hernandez, his wife and daughter in a two-story, brown duplex that backs up to a playground.
The daughter, he said, was likely in her late teens.
Mr. Wollick said he never heard of any problems involving Mr. Hernandez and any children of the working-class, tree-lined neighbourhood, where residents were setting up on Thursday for a Little League baseball fundraiser.
"These people were like church mice; you never heard them," said Mr. Wollick. "I would never think of this guy as doing something like this."
He said the family regularly attended church and kept a tidy house. Mr. Hernandez might have a beer occasionally, he said, but never seemed a big drinker.
Another neighbour, Ashley Kabbeko, 25, who lives next door, said she saw two detectives drop off Mr. Hernandez's wife and daughter Wednesday afternoon, but has not seen any members of the family since.
"He was real nice," she said. "He was always smiling."
A source said Mr. Hernandez appeared willing to speak about the killing because he has been diagnosed with cancer and was facing problems in his marriage. He has confessed to his role in the case to both his current wife and ex-wife, the source said.
Mr. Kelly, in a media conference on Thursday, said he had no information on whether Mr. Hernadez's confession was motivated by health or marital concerns.
Manhattan District Attorney Cyrus Vance re-opened the case in 2010, after a series of dead-ends frustrated a string of investigators. Etan was one of the first missing children in the United States to have his photograph printed on milk cartons, and his case helped fuel an intense national outreach campaign for missing children in the 1980s.
Long targeted as a suspect in the case was Jose Antonio Ramos, a friend of Etan's babysitter who was later convicted of child molestation in a separate case in Pennsylvania. He is due to be released from prison in November.
In a 2004 civil suit Etan's parents brought against Mr. Ramos, a New York judge found him responsible for the boy's death, a charge he denied.
Etan's family members last month asked the media to respect their privacy as the days-long dig was under way just 100 yards (91 metres) from the home where they still live.
Authorities tore through the floor of a workshop used by a handyman, Othniel Miller, now 75, who had paid the boy to help him with chores. Mr. Miller was questioned by police but was not charged with a crime.
On Thursday, dozens of reporters and camera crew milled outside the Patz apartment above a trendy street of high-end boutiques and restaurants. No one answered the door to the apartment.
"I just hope they get some resolution after all these years. It's just a horrific thing," said Carla Seal-Wanner, 58, an animator and mother of three who moved to the neighbourhood in the early 1980s. "It was very much still in people's minds. Of course, it always was lurking as the history of the neighbourhood."
